This conversion did not function D correctly when you specified field=+value (addition of one bit).H Since I no longer have access to an IA64 machine, I cannot compile theO newer versions. I successfully compiled the 4.0 version to IA64, so it shouldS be possible to build dix0410 and later on IA64, if you have the fortran compiler.V0411 13-sep-2005B1.

Added show release_notes commandV0430 21-jan-2006H1. Greatly enhanced the record search. You can now search in (fields of)E multiple records with a lot of compare options. See the help about record_seaches.J2. In the interactive mode , the FIND and SEARCH commands have be changed.L THe FIND now searches data in the record, the SEARCH records in the file.B3. Added the SHOW SEARCH, SET SEARCH and the EDIT SEARCH commands.D4. Added the set integer size 8 on alpha and ia64 (sorry not on vax)G This allows symbols with 64 bit integers and all operations on them.: Fields with 64 bit integers have always been supported.!5. Enhanced the CSV in dump/file.K6. Included a DUMP command in interactive mode (including a CSV qualifiers)K7. There was a problem with the make-file. The procedure used an undefined & symbol SAY. This problem is solved.G8. There was a link problem with older (pre 7.3 Alpha) versions of VMS.J DIX used the routines OTS$CVT_T_S (concert text to bin for REAL*4 IEEE)E and OTS$CVT_T_T (convert text to bin for REAL*8(IEEE). I replaced ; these routines, and this problem should no longer occur.V0500 1-may-2006O1. Enhanced the wrap. Sometimes DIX would wrap output lines when not necessary.,2. Enhanced qualifiers for the DUMP command.K3. Changed the record header for dump/file to a one line display containingL recordlength,recordnumber,vfc_record size and RFA. The output to symbols  is still separated. 4. Fixed some integer*8 problems"5. Added the FILECOUNT() function.E6.

Fixed a small problem with the /next_record search qualifier.H9. Added the /FORMAT qualifier and the SET/SHOW format command, to allow8 the display of unprintable data in character strings.O10. Fixed a bug in the raw screen display with scrolling. If the data contained2 more than one screen, the display went wrong.Q11. Inluded the MOUSE-usage on a decwindows-terminal, and menu_key in screenmode.G12. Included the context for a key definition. This allow you to define7 keys with different meaning in different screens. <13. Added funtions BTEST, IBSET and IBCLR (bit manipulation)Q14. There was a problem with hex input for character fields, that has been solved.15. Fixed some (non-)alignment problems on VAXW16. Fixed the (signed) display of bytes and words. They were converted as unsigned data17. Included the DEMO modeU18. Added the RFA of the current record to the header in screen mode (thanks to Hein)J19. Fixed an error when doing screen_print and leaving the filename empty./20. Added binary and octal display in all modesH21. Added support for previous record for an indexed and a relative file+22. Changed the key PF1-H to PF4-H and v.v.K23. Changed the search order for .des files, first currentdir, then filedir' then userlib and finally systemlibU24. Added fieldnames for dates (none, expired etc). If you have your own descriptionsK with date types, make sure you add the [0=none] to the description line 25. Added new datatype deltatime)26. Added symbol substitution for verbs. -27. Added the f$mode and the f$radix function>28. Added the decimal symbol type and the [u]decimal datatype.H29. The set strict command is now per level. Each @file can set its own. 30. Added the f$verify function.C31. Removed the "onelinecommand" from interactive mode, but added a2 /command=("command1","command2",..) qualifier.v0510 8-jun-2006F1. Added the #IFDEF function for conditional expansion of descriptionsD2. Fixed a problem with "fixed" symbols. If you explicitly declare aH symbol with a type, DIX did not always forbid you to change the type.E3. Added the /FAST qualifier for the search commands. If you use thisE qualifier, DIX will bypass RMS, and it may be faster. See the help dix/help record_search/fastF4. Allow /record on indexed files, together with the /key, you now can read record "n" on key "key"I5. Allow search selection on record_length with lt,le,eq,ge,gt and range.:6. Included a /rfa= qualifier to select a specific record.G the previous /rfa qualifier is replaced with the /mark. See the helpV9999Known restrictions.1.H When using GOSUB, the RETURN statement must be at the same syntax levelF as the entry point. This is NOT checked, and violation will result inH strange behaviour. This problem does not exist with the CALL statement. Example IF (exp) THEN Statement WHILE (expr) Statement GOSUB test ENDWHILE test: - Statement |9 ENDIF | Gosub/return block runs into an endif! statement | Not supported RETURN - IF (exp) THEN Statement WHILE (expr) Statement GOSUB test ENDWHILE= goto lab1 Do not runinto, since RETURN will be unexpected test: -? statement | Gosub/return block at the same syntax level% Statement | This is supported RETURN _  lab1: ENDIF "2.
